Greubel Forsey’s first launched their Masterful Gmt in 2011 and from then on having mastered the tourbillon, Robert Greubel and Stephen Forsey have continued to investigate and reinterpret other horological mechanisms,In bringing the Quadruple Tourbillon and the GMT mechanisms together.
GMT Quadruple Tourbillon
For thje new GMT Quadruple Tourbillon Forsey not only accomplished a major technical feat that led to the creation of a new hand-wound calibre comprising 705 parts, including three fast-rotating barrels. The Inventor Watchmakers also tackled this challenge from an architectural angle to create a timepiece in which the three-dimensional approach is expressed on many levels. The main hours/minutes dial between 1 and 2 o’clock forms the highest point of the dial,where it is underlined by the subtle asymmetry of the case and complemented by a 72-hour chrono metric power-reserve display. The next level is it at 4 o’clock,with the coaxial small seconds and second time zone display which is adjustable in one-hour increments by means of a pusher. Located between 8 and 9 o’clock,observers can admire the spectacular sight of the Earth in motion, surrounded by a fixed 24 hours ring around the Equator and displaying local time for all the longitudes – simultaneously taking account of the day/night indicator (on respectively light/dark zones).
GMT Quadruple Tourbillon Caseback
Universal time is visible through the case back, with a fixed 24-hour scale bearing day/night zones and a disk with three-letter abbreviations of 24 cities representing the various time zones. Watchbazar loved the case back which provides a chance to admire the Quadruple Tourbillon as well as frosted bridges with jewels set in gold chatons.
GMT Quadruple Tourbillon will be available in edition of 66 pieces. The first edition of 11 of which are in white gold, numbered from 01/11 to 11/11 on a plate in the center of the dial.Comes on a black hand-sewn alligator leather strap with an 18kt white gold folding clasp, hand-engraved with the GF logo.
